Find the coordinates of the point 3/10 of the way from A to B.

Answers

Final answer:

To find a point that is 3/10 of the way from point A to B, we scale the vector from A to B by 0.3. To find the x and y coordinates of this point, we use the formula X = x1 + 0.3 * (x2 - x1) and Y = y1 + 0.3 * (y2 - y1) respectively.

Explanation:

The question asks us to find the coordinates of a point that is 3/10 (or 30%) of the way from point A to B. This involves using the idea of vector addition and scalar multiplication in mathematics.

Let's represent the journey from point A to B as the vector AB. You can consider vector AB to be generated by some coordinates (x1, y1) at point A and some (x2, y2) at point B. If we are trying to locate a point that is 3/10 along the way from A to B, it is like scaling the vector AB by 0.3 (3/10).

To find the x and y coordinates of that point, we would calculate it as follows:

X-coordinate = x1 + 0.3 * (x2 - x1)
Y-coordinate = y1 + 0.3 * (y2 - y1)

As a result, by substituting the coordinates of point A and B into these equations, we can find the coordinates of the point that is 3/10 of the way from point A to B.

Final answer:

To find the coordinates of a point 3/10 of the way from point A to point B, we can use the concept of midpoint formula. The coordinates of A are (11,7) and the coordinates of B are (-3,-6). Using the midpoint formula, we can calculate the coordinates of the desired point are (6.8, 3.1).

Explanation:

To find the coordinates of a point that is 3/10 of the way from point A to point B, we can use the concept of midpoint formula. The midpoint formula states that the coordinates of the midpoint between two points (x1, y1) and (x2, y2) can be found by taking the average of the x-coordinates and the average of the y-coordinates. In this case, the coordinates of A are (11,7) and the coordinates of B are (-3,-6). So, we can find the coordinates of the point 3/10 of the way from A to B by taking 3/10 of the difference between the x-coordinates and adding it to the x-coordinate of A, and taking 3/10 of the difference between the y-coordinates and adding it to the y-coordinate of A. Let's calculate it step by step:

x-coordinate: (3/10)(-3 - 11) + 11 = (3/10)(-14) + 11 = -4.2 + 11 = 6.8

y-coordinate: (3/10)(-6 - 7) + 7 = (3/10)(-13) + 7 = -3.9 + 7 = 3.1

So, the coordinates of the point that is 3/10 of the way from A to B are (6.8, 3.1).

The speed of light travels at a rate of approximately 3.0 * 10^8 meters per second. How far, in meters, does light travel in 10^5 seconds?

Answers

Answer:

Step-by-step explanation:

There is a few ways to go about doing this problem. I am going to setup a function.

x = seconds

f(x) = distance = How far

f(x) = (3.0* 10^8) x

Insert 10^5 where x is located

(3.0* 10^8) x

Multiply

(3.0* 10^8) (10^5)

Do the math

(3.0* 10^8) (10^5) = 3 * 10^13

Firm A and Firm B have debt-total assets ratios of 65 percent and 45 percent, respectively, and returns on total assets of 5% and 7%, respectively. Which firm has a greater return on equity

Answers

Answer:

Firm A

Step-by-step explanation:

D = Debt

A= Asset

E = Equity

ROA = Return on assets

ROE = Return on equity

For Firm A:

$(D)/(A)=0.65\n(E)/(A)=1-0.65=0.35\nROA = 0.05\nROE=(ROE)/((E)/(A))=(0.05)/(0.35) \nROE=0.1429=14.29\%$

For Firm B:

$(D)/(A)=0.45\n(E)/(A)=1-0.45=0.55\nROA = 0.07\nROE=(ROE)/((E)/(A))=(0.07)/(0.55) \nROE=0.1273=12.73\%$

Therefore, Firm A has a greater return on equity.
